I would agree with Tfox. I would pay more attention to the reflex than I would the brace height. I don't buy into the shorter powerstroke thing being more forgiving. The only reason I would consider brace height is for clearance issues. Reflex is more important because it will affect the amount of torque that gets induced to the riser at full draw.

Some say shorter draw archers are at an advantage because we have a shorter power stroke and the arrows is on the string for a shorter amount of time. Giving you less time to mess up the shot. Same thing with higher brace height bows. I personally think this is a bunch of crap and not thought out very well. After you pull the trigger the arrow is gone and in the target 20 yards a way before you can blink your eye. There is no way you had time to mess the shot the up while the arrow was in motion. Humans just don't react that fast. Anything you did wrong you did it before you released the arrow, you just didn't know it. That would be like saying a longer barrel on a rifle would be less forgiving because the bullet was in it longer, ya right! When you mess up a shot with a bow or a gun it is due to improper form and anticipating the shot. Like punching the trigger or looking around the sights to see where you hit. I have seen people do it with bows and guns. You think you are doing it after the shot, but you actually start moving before you pull the trigger and just don't realize it.

Get a good wrist sling and learn proper follow thru. Blind bale shooting helps alot as well. As does dry firing a rifle. This helps you get over anticipating the shot and you can concenrate on aiming instead. If you do it right you can see the arrow fly to the target, there is no need to drop your bow arm or look around the sights.

Good luck,
